Question options:
a. RAID 0
b. RAID 1
c. RAID 5
d. RAID 6
e. RAID 10
Answer:
d. RAID 6
Explanation:
RAID is Redundant Array of Inexpensive/Independent Disks. RAID combines low cost physical hard disk drives in one hard disk drive. RAID is used to achieve data redundancy(data backup but with synchronization) or improved performance or both.
To get what the director requires he would need to use RAID 6. RAID 6 is RAID level optimized to achieve data redundancy but with slow performance.
Answer:
import java.util.Scanner;
public class Solution {
public static void main(String args[]) {
Scanner scan = new Scanner(System.in);
System.out.println("Enter your value");
int value = scan.nextInt();
greaterThanFive(value);
}
public static void greaterThanFive(int userInput){
System.out.println(userInput > 5);
}
}
Explanation:
The first line import the Scanner which is use to enable to accept user input.
The class is defined as Solution in the next line. The main method is declared in the next line which signify the beginning of the program.
Then, a scanner object is declared called scan in the next line. Then a prompt is display to the user to input a value. The user input is stored in the variable value. The value is then passed to the method greaterThanFive.
The method greaterThanFive is declared and have just one parameter, the userInput. Inside the method, we output if the userInput is greater than 5 using the logical operator (>).
Answer with Explanation:
Part 1)
The given sine wave is as
The graphical representation of the wave is shown in the attached figure:
Part 2)
For a general wave equation 
'A' is defined as amplitude of the wave
is defined as phase of the wave
Upon comparing with the given wave function we observe
1) Amplitude of the given wave is 3
2) Phase of the given wave 
The correct answer is false
